Two Russians that had been informing Ukrainian intelligence agencies of the Black Sea Fleet actions were detined in Simferopol, Crimea.
The Federal Security Service of the Russian Federation reports that it has detined Russian citizens Sukhonosova Anna Stanislavovna and Dolgopopov Dmitry Alexandrovitch. The latter was a member of the Russian military stationed in Crimea. During the questioning he admitted passing sensitive data to the Ukrainian Intelligence. Charged with treason, they are facing a 20 year prison sentence.
According to RIA, Crimean government considers the reason Ukraine engaged in espionage was because blocking and threatening Crimea proved inefficient.
